This is the first "cheap" lens. Some cloudiness, dust, and mold are visible. It's well-made for a "cheap" lens, and I liked it, but I'm selling it because I have too much equipment. Sample photos taken with a full-frame camera are included. It seems to be working fine. High-quality 50mm F1.8 lens, allowing for bright shooting at f/1.8. - Brand: Canon - Model: 50mm F1.8 - Focal Length: 50mm - Aperture: F1.8 - Country of Manufacture: Japan Thank you for looking.
